 Overview:
  Chipmunk Guestbook is prone to an SQL-injection vulnerability
  because it fails to properly sanitize user-supplied input before
  using it in an SQL query.

  A successful exploit could allow an attacker to compromise the
  application, access or modify data, or exploit vulnerabilities in
  the underlying database.
